O-Train Extension overview

Updated on May 29, 2024

Welcome to the O-Train Extension. We’re upgrading transit in Ottawa. This project extends the O-Train farther south, east, and west.

Explore this page to learn about the project, its milestones, and the benefits to our growing city.

The O-Train Extension will foster connectivity, sustainability, and economic growth. Let's transform Ottawa's transit together.


The O-Train Extension is underway. We’re enhancing transit across Ottawa by: 

  • Extending Line 2 South to Limebank and Airport Stations
  • Stretching Line 1 East through Orléans to Trim Station
  • Expanding Line 1 West to Algonquin Station
  • Adding the new Line 3 to Moodie Station

We’re introducing cutting-edge Stadler FLIRT trains and new and upgraded stations. With reliable connections, it’ll be easier to explore more of your city.

Line identities

1 2 3 4

We carefully designed the identity of rail lines to simplify wayfinding and enhance recognition. This helps customers develop navigation muscle memory. The future O-Train network ensures a seamless and intuitive experience by:

  • Clearly distinguishing the lines using different colours
  • Creating meaningful, memorable, and practical station names
  • Providing consistent and coherent signage

Line colours

Colour plays a crucial role in our design. We use bold, eye-catching colours. The colours reflect the energy and vibrancy of our growing city. These colours are used consistently in maps, signage, and schedules. 

Intuitive wayfinding is key to seamless navigation. For this reason, we’ve defined distinctive colours for each O-Train line. 

This visually striking approach helps riders get familiar with their regular routes. It also lets them identify their desired lines quickly and easily. 

Quick facts

  • Lines 1 and 2 will keep their existing colours
  • Lines 3 and 4 will have brand new colours
  • The colours of the bus services will remain the same for consistency

The identity of new O‑Train lines is distinctive, accessible, and user-friendly.

Key factors

  • Unique line colours for easy differentiation. We’ve added numbered icons for more clarity.
  • Accessibility:
    • High contrast and colour-blind friendly
    • Line identities chosen with extensive stakeholder input, including the CNIB
  • Colours are adaptable across all formats they’re displayed including:
    • Digital screens
    • Maps
    • Printed signs
    • Station signs
    • Low-light
    • Backlit signs
  • Alignment with service design (how lines would be shown in context):
    • Lines 1 & 3 mostly run parallel
    • Line 4 connecting to the airport is linked with Line 2
  • Numbers and colours that are easy to identify and remember

Our approach

We considered accessibility, distinctiveness, and visibility. Unique brands for each line helps you spot your lines more easily. Bold colours remain visible under various lighting conditions. 

The result is a user-friendly and visually appealing wayfinding system. It will allow riders to explore Ottawa with ease.

Station names

Choosing the right station names is crucial to help riders navigate to their destinations. We selected the names for new O-Train stations in consultation with: 

  • Ward Councillors
  • Members of the public
  • A working group led by the Transit Commission Chair

While selecting these names, we ensured they were:

  • Geographically meaningful
  • Easy to understand in both English and French
  • Easy to pronounce and write
  • Unique and distinct from other stations and city locations
  • Consistent with Transitway station names

New naming examples

These examples demonstrate our approach to naming the new stations: 

Carling Station becomes Dow’s Lake Station

Renamed to highlight nearby Dow's Lake and the surrounding neighbourhood.

Dominion Station becomes Kichi Zìbì Station
  • Aligned with nearby Kitchissippi Lookout
  • Named after adjacent Ottawa River
  • Uses an Algonquin spelling for added cultural relevance

Station signage

Station entrance signs

O‑Train Extension station entrance signs will feature distinct colours and numbers for improved visibility.

  • Lincoln Fields Station, serving Lines 1 & features a red circle with a white "1" and a gold circle with a white "3"
  • Bayshore Station, served by Line 3, displays a gold circle with a white "3"
  • South Keys Station, on Lines 2 & 4, reveals a green circle with a white "2" and a blue circle with a white "4"

The signs were designed for effortless recognition. They feature clear, highly visible, and easily identifiable markers.

Direction‑of‑travel line maps

You’ll find these easy-to-use maps as you arrive at the train platform. These signs tell you where you are along the O‑Train line. They let you know whether you’re heading the right way by showing all upcoming stations in your travel direction.

Here's a preview of what you can expect:

If you’re heading south on Line 2 at Carleton Station, you’ll see the map just before you enter the platform. Line 2 is shown as a white number 2 inside a green circle, and a green line on the map.

To help you navigate easily, this map provides valuable information, such as: 

  • The train’s direction of travel
  • The next station
  • Transfer points

System design

We’re building 24 new stations along the entire extended O-Train network. These stations will connect neighbourhoods and improve access for many residents.

Our ambitious green approach focuses on:

  • Low carbon-impact construction
  • Energy efficiency
  • Long-lasting and adaptable buildings
Sustainable mobility

Enhanced connectivity for a vibrant community

The O‑Train Extension project goes beyond new stations and tracks. We're rejuvenating public spaces and building new pathways. These facilities seamlessly fit into the surrounding community to enhance the quality of life for locals.

Promoting active transportation

We’re investing roughly $20 million in multi-use pathways (MUPs), cycle-tracks, and pedestrian bridges. These will enrich our City's vast pedestrian and cyclist network. This investment improves access across our network.

  • Bicycle parking with room for growth at all stations, with 80% of provided spaces covered

These design features create a safe and accessible experience and make public transit a convenient transportation option.


Revamping public spaces for greener commutes

We are improving station access for nature-friendlier forms of transportation, like walking and cycling. Most stations will also have direct bus connections. This will make it easier to access the O‑Train from farther away.

The system design encourages residents to walk, wheel, bike, or bus to the O-Train. In the new network, 77% of Ottawa's residents will live within 5 km of a station. This could be a 10-minute bus ride, a 20-minute bike ride, or an even shorter trip if you live closer.
